McGill had an interception and 12 pass breakups for Utah this season, his only full season with the Utes. McGill played in five games after transferring in from a junior college before being injured in 2011, then missed the 2012 season with an injury. He played safety in 2011.

Mayock said the rise in taller corners should not be a surprise. With the move to more big-bodied wide receivers in the NFL, Mayock said teams are looking for "longer body frames" in their corners. He said some teams are willing to use corners who are "a little less quick-footed and explosive" as long as they are big.

The other corners who are at least 6-0 are Nebraska's Stanley Jean-Baptiste and North Carolina State's Dontae Johnson at 6-2, Lindenwood's Pierre Desir at 6-1 and Liberty's Walt Aiken at 6-0.

Lindenwood is a Division II school in the St. Louis suburbs. Desir, who should run in the 4.5 range in the 40-yard dash in pre-draft workouts, showed well at last week's East-West Shrine Game.
